Association between turnover-based and unified TMV-based classification of ROD

Turnover-based classification	Unified TMV-based classification
	Low turnover—AD	Normal turnover—mild HPT/normal	High turnover—HPT	Total
Low turnover	6	9	1	16
Normal turnover	0	0	7	7
High turnover	0	0	3	3
Total	6	9	11	26

In cases of low turnover/adynamic bone disease all the subjects matched to turnover-based classification. In cases of hyperparathyroid bone disease, only 27% of the subjects matched

Of 26 subjects, only nine matched, 34% (Kappa’s test was 0.19). Patients with normal turnover/normal bone or mild hyperparathyroid bone disease were classified as low turnover and patients with high turnover/hyperparathyroid bone disease were classified as normal turnover when using Malluche’s reference values for normal bone turnover

AD adynamic bone disease, HPT hyperparathyroid bone disease
